To wZ whom it' may concern:

Be it known that l, WiLLIAM @.HART- MANN, a citizen of the UnitedStates, resid ets.

ing at Lansing, county of Ingham, and State .of Michigan, (having mypost-ofoefaddress at Lansing, Michigan,) 'have invented certain new anduseful Improvements in Driving Mechanism for Centrifugel Seperetors, ot'which the following is e specification.

M invention relates to driving mechenf ism or centriugaleream-seperat'ors and its 1 pnrpose 1s to make a sim le and efficientdevice by the operation oi which the gearing and ,driving mechanism willinstantly be come disengaged from 'the Wormspindle when the propellingforce ceeses to he applied and the bowl will continue its revolutionsindependently of the gearing, which will re- Inain'at rest.

Fi ure lis e vertical sectionl of the wormspi le, worm-wheel, end wormof e centrihigal separator to which my device is applied. Fig.. 2 is anelevation of the Worm and ratch- Figs, 3, 4, end 5 are detaiied views ofthe different parts oi' `Figs. l end 2.

A, Figs. 1 end 2, is a worm-spindle ci a ceriw trifugal separator, tothe ue per end of which the bowl-stem 0 is attached 1n the usuel menner.The shaft revolves et its lower end on the double hall-bearing i?, whichmay he ed justed by Ineens of the screw (.3. A worm B,- cut in the usuelform, is adepted to slide sind revolve freely on the worm'epindie A.Worm carries at its lower end e collar R, iriving' on its lower faceratchet-teeth L, adopted to engage with similar ratchet-teeth L on acoller C, firmly secured by e. pin D or other 'suitable Ineens to thewormspindle A. A.

shoulder H is formed 'on the worin-spindle A to limit the upwardmovement ci the worm B. While it is not en essentiel feature of myinvention, I prefer to introduce bushings M near each extremity oftheworin B for the purpose of getting a smoother freer motion of t e worinon the worm-spindle A.

A coller or enlarged portion Ii is formed at the upper extremity of theworm B to engage with e depression formed-in e spring F, so that WhentheWorm is raised it will be held in its position until pressed downward bythe operation of the Wormwheel S.

The operation ofthe device is as follows:

Suppose the Worm to hc in the position This shown. in Fig. 3, in whichthe worm is held in its elevated position by the springt?. lf theworrn-wheel S is caused to revolve in 'the direction indicated by thearrow X, theust effect will he te press the wombgeer B dov/nf ward,releasing 1t from the spring l?, end to ineke :it revolve on theworm-spindle A, thus bringing the retehet-teeth L into engage nient withthe ratch.ettee1th4 L end compeh ling the Worin-spindle A. to revolvewith the worm. if, however, the worrn'`-wl1eel S is' retarded or stoppedor given e reverse me tion in the direction indicated by the arrow Y,the teeth ot' the wormv B immediately act on the teeth ofthe wheel S asinclined lanes,

raisin the worm E until it is stopped y the shoul er H, in whichposition the ratchet L is disengaged from the ratchet L', leaving theworm stationair ,the worin-spindle A continuing .its revo n-tions hyits'vc'wn inoN lmentui'n until it grs-duelly comes to rest.

Of course the form ci the retchet-teeth L and il may he changed, or e.pin may loe cm ployed in place of the teeth'without departing from thespirit ci my invention;
